Son Bhandar caves is another cave located in Rajgir in Bihar. The other one is Saptaparini caves.
They belonged to the Jains. The caves are generally dated to the 3rd or 4th century CE, based on the dedicatory inscription found in the largest cave which uses Gupta script of the 4th century CE. However, some experts put this cave at 3rd century BC.
The main cave is rectangular with a pointed ceiling, and the entrance is trapezoidal, reminiscent of the structure of the Barabar Caves (the first artificial caves of India, dated the 3rd century BCE).
It is maintained well., compared to Saptaparini caves. Nearby is another attraction which is glass bridge which is of 200 feet height and can accommodate 40 people at a time. Besides Glassbridge, there are also other adventure activities like flying fox, zipline, wall climbing etc., to attract tourists.
